Vulcan 80C cable hammer, S/N GH-1070, taken 17 January 1979 at the Chattanooga plant. Vulcan was relatively late in the life of the product line in putting cables on the differential-acting hammers, and when it did the “pockets” (which you can see on either side of the cylinder just below the steam chest) made it impossible to jack the cables. Both Raymond and Pile Hammer Equipment had better methods of cabling the Super-Vulcan hammers.
Vulcan 80C hammer driving 55′ long 12″ concrete piles for the Bay Area Municipal Utilities District Sewage Treatment Plant in Oakland, California; H.F Lauritzen Company was the contractor. This is a good example of a fixed leader arrangement, which offers the best support for hammer and pile alike. This is especially important for concrete piles.
Some general arrangements, Chicago and Chattanooga, are shown below.
